[Freeswitch-users] Efficiency/Performance of mod_xml_curl Versus Flat XML Files

We are considering converting our flat XML files to database lookups on the same machine. It appears mod_xml_curl can be used for this purpose, but we are wondering how efficient mod_xml_curl is? We are concerned that it will increase CPU loading and thus slower response time, especially for dialplan call routing. Does anyone have any opinions or recommendations? Best Regards, Jerry
